The scale of star brightness is the 'magnitude'. The definition of the magnitude is: A change of six magnitudes equals a factor of 100. So one magnitude change is a factor equal to the 6th root of 100 = about 2.15443 (rounded)

∙ 14y agoThis scale is known as the magnitude scale. The scale is backwards in that brighter stars have a lower number. The magnitude scale is split into two sub categories, apparent and absolute. Apparent is how bright a star is as we see it, often reduced due to interstellar dust or our atmosphere. While absolute is how bright it would be if there was nothing between us and the object.

The lower the number, the brighter the star. Like the Richter scale of earthquakes, the scale is logarithmic; a change of "1" indicates a difference of a factor of 10.
For example, the bright red supergiant star Betelgeuse, at the upper left corner of the constellation Orion, has an absolute magnitude of -5.14, and an apparent magnitude of 0.58. Our Sun has an absolute magnitude of 4.83, and an apparent magnitude of -27.6.

A star brightness is called?
Apparent magnitude.
How are the brightness and temperature related?
brightness and temperature are both related because brightness is actually tempature. However the system has become more refined. Instead of just looking at the star and determining magnitude one or magnitude two, an astronomer measures the brightness of the star using a device called a photometer. The photometer counts the number of photons coming from the star. This photon count is then compared to the photon count from a star whose magnitude is known. An accurate magnitude can then be calculated.
Is a high magnitude star more dense than a low magnitude star?
Magnitude is a measure of brightness, there is no relationship with density.
Use apparent magnitude in a sentence?
The apparent magnitude of a star is a measure of its brightness.
What is the apparent brightness of star vega?
The apparent magnitude of Vega is 0.03. The absolute magnitude is 0.58.
What is a star brightness called?
the brightness of a star is called it's magnitude
What is the measure of the star's brightness?
The measure of a star's brightness is its magnitude. A star's brightness as it appears from Earth is called its Apparent Magnitude.Star's brightness is measured by there magnitude.
What the measure of a stars brightness called?
The measure of a star's brightness is its magnitude. A star's brightness as it appears from Earth is called its Apparent Magnitude.Star's brightness is measured by there magnitude.
What part of a star is called magnitude?
The magnitude of a star refers to its brightness.
What is it called when brightness is how bright a star seems or looks?
The brightness of a star to an observer on Earth is called it's Apparent Magnitude. The intrinsic brightness of a star is known as it's Absolute Magnitude.
A star's brightness is the brightness seen by humans on Earth. A star's brightness is its actual brightness and does not depend on where the star is viewed from.?
The brightness as seen from Earth is called the "apparent magnitude".The real brightness (defined as the apparent brightness, as seen from a standard distance) is called the "absolute magnitude".
The actual brightness of a star is called?
magnitude
A star brightness is called?
Apparent magnitude.
What is star's magnitude?
The magnitude is the brightness of the star.
Name for How bright a star is from the earth?
The brightness of a star is called visual magnitude. The lower the visual magnitude is the brighter the star is.
What do you call the brightness of a star?
its called the magnitude dumb *ss
What term is used to describe a star's brightness?
It is called Vmag. This is the visual magnitude of the object. Visual magnitude is a scale used by astronomers to measure the brightness of a star or other celestial object. Visual magnitude measures only the visible light from the object. The lower the V-MAG the brighter the star. You can go to http://seasky.org/pictures/sky7b14.html to learn more.
